        <p>Constructs a new Element implementation that checks and converts values for a
particular field type, as appropriate.</p>
<p>An Element represents a single value: either the value of a singular field,
or a value contained in one entry of a repeated field or map field. This
class does not implement these higher-level concepts; it only encapsulates
the low-level typechecking and conversion.</p>
